Broadband Internet services are not widely available in rural areas such as Mendocino County in California. Why not? One answer is that, due to the spare populations in these areas, it is expensive to deploy traditional network technologies such as fiber. As a result, there is often only a single incumbent Internet service provider serving these areas, stifling competition and driving up prices...

This paper investigates how broadband penetration affects economic growth. A macroeconomic production function with a micromodel for broadband investment is used to estimate the impact of broadband infrastructure and growth. The results indicate a significant causal positive link especially when a critical mass of infrastructure is present. The scope of this research is the 15 European Union co...

A novel type of circularly polarized broadband antenna consisting of a modified circular wideslot aperture and an L-shaped feed probe is introduced. The modified circular wide-slot is partially covered to generate circular polarization with broadband characteristics in the axial ratio. Variations in both the axial ratio and the S11 characteristics of the device are investigated and radiation pa...

Measuring broadband performance on a large scale is important for network diagnostics by providers and users, as well as for public policy. Understanding the various scenarios and users of measuring broadband performance is essential to development of the Large-scale Measurement of Broadband Performance (LMAP) framework, information model, and protocol. This document details two use cases that ...

This paper looks at the extent to which the bandwagon effect played a part in Digital Subscriber Line (DSL) broadband adoption combined with the regulatory measures, the slowdown in the cable industry and the changes within the telecommunications industry in the United Kingdom (UK). The dynamics of broadband deployment, broadband adoption against a real-world supply-demand equation and the fact...

In this article an Archimedean spiral antenna is designed and analyzed that has good operation in broadband application. By analyzing this design, the effects that different parameters have on antenna operation will be studied and ways of optimization will be found.  Influences of cavity height and number of turns to obtain good matching and gain in a frequency interval of 4 to 18 GHz will be d...

This paper represents design broadband impedance matching circuit for Coupler to improve power transfer efficiency in the broadband power line communication (BPLC) systems. The Butterworth gain function equalizer is used to design broadband matching circuit. A practical PLC Coupler impedance matching circuit is designed, and the characteristics for S11 and S21 of PLC Coupler are enhanced compar...

I f Al Gore invented the information superhighway, then President Bush ought to be able to raise the speed limit. Or so Bush seemed to be saying on Friday when he called for extending high-speed Internet to every U.S. home within three years. “This country needs a national goal for broadband technology, for the spread of broadband technology,” Bush said while campaigning in Albuquerque. “We oug...
